Why did Android download a WebP file?
Many websites serve WebP because it can reduce image size, so saving an image from a browser may keep that format.
Use this Android WebP workflow when a downloaded image from Chrome, a chat app, or a web save needs to work in software that only expects JPG. Android has long supported WebP playback, but some forms and office tools still reject .webp files. This page turns the selected WebP into a practical JPG copy while preserving the quick local workflow expected from a phone or tablet download.

JPG is accepted by more older upload forms, document tools, and support portals than WebP.
No. JPG has no transparency channel. Use WebP to PNG when transparency matters.
